I'll use the 4 hours, that's one new spell, 40 gp spent. At this rate, I'll make sure every minute of downtime is used towards copying spells. That's fine, since it works well with Elrembriel's personality and motivation. Just don't expect much of a social life.

Ready to go, with slightly changed spell list. I'll keep the cash for now, angling for another 700 gp to buy something really nice later
